1280 x 1024 on desktop, 1400x1050 on the laptop.
1152x864 is a traditional Mac resolution, too, although most modern PCs can use it.
Reminds me of a VP at my last job, who complained that the company website I was responsible for looked crappy on his new top-of-the-line Dell with a 21" monitor. I asked him what resolution he was using. He replies, 640x480, so he doesn't have to wear his glasses. I told him to either suck it up and deal with it, or switch to at least 800x600.
